      Thanks for the reply.  :)

      I don't believe I am running in to this as I increased my mbuf when I first installed pfSense, I have this in my /boot/loader.conf.local:

      kern.cam.boot_delay=10000
      hint.acpi.0.disabled=1
      legal.intel_ipw.license_ack=1
      legal.intel_wpi.license_ack=1
      kern.ipc.nmbclusters="131072"
      

      However I don't think I actually looked at mbuf the last time this happened, so I can't rule it out 100%.

      Edit:
      Looks like mbuf is fine, it's only at 10%:

      $ netstat -m

        If you have the bridge interface set as LAN have you spoofed the MAC? This doesn't match your symptoms but if you don't spoof the MAC address it will be assigned a random one that may change betweem boots. Windows then sees that as a new DHCP server and will set it's firewall appropriately. Something to watch out for.

        My first suspect here would be Snort. Are you running it on LAN?

          I have spoofed the LAN bridge interface, yes.
          I do run Snort on LAN, but the configuration has not changed compared to when it was running on 2.1.0.
          The Snort version did change though I think.
          I will disable it on LAN and see if that makes a difference.

          Thanks. :)

            Disabling Snort on the LAN side did not make a difference.

            Strangely, unchecking the Snort Interface - General Settings - "Enable or Disable" check box and saving, changes some of the settings.
            I did a config diff after I re-enabled and these items were all different:

            • blockoffenders7

            • cksumcheck

            • fpm_search_optimize

            • fpm_no_stream_inserts

            • suppresslistname

              I have tried a few more things.
              While being unable to connect with my main desktop and having it set up with a static IP:

              • I stopped all services (using status\services).

              • I disabled all the block/reject rules on the LAN interface.
                The only ones there were pfBlocker reject rules.
                The firewall log was not showing any LAN rejects.

              • Reloaded filters (using Status\Filter Reload)

              • Reset states (using Diagnostics\Sates)

              • Killed of a number of processes that were killable (using "kill" in Diagnostics\Command Prompt)

              After this, I still was unable to ping my main desktop either from pfSense or from another PC.
              After a pfSense reboot however, it connected just fine.

                Rogue DHCP server on your LAN? Can cause odd symptoms like this. Especially as a delay is involved. Is it of the order of your DHCP lease time?
                Doesn't explain why a static IP doesn't work though. Some other local IP conflict then perhaps a rogue device with the same IP as the pfSense LAN or your device.

                Try running a packet capture on LAN to see if your pings are arriving or responses being sent.

                Steve

                Edit: Typo, rogue not rouge!

                  Thanks for the suggestions.

                  I would think that being unable to connect while having a static IP would eliminate any sort of DHCP problem (like you said).
                  The two other devices that could have DHCP servers running, my NAS and WAP have them both disabled, and the problem still occurs with them off.
                  I have my devices set up with static leases, including the main PC.
                  The lease time for the DHCP server on pfSense is left at the defaults, which is 2 hours I think.
                  When the PC is connected, the DHCP logs show a DHCPREQUEST once an hour, and a DHCPINFORM and DHCPACK once every 10 minutes.
                  I haven't quite figured out the exact threshold is for this problem to occur, but I think it is somewhere past 4 hours after powering off a PC.
                  I hadn't kept track of exact times between power off and power on, but I have started doing that now.
                  So far, the longest time between power off and power on and still being able to connect has been 3 hours and 40 minutes, but I don't have a lot of data yet.

                  An IP conflict/rogue device is an interesting thought, however I have a limited set of devices (about a half dozen or so) and most are set up with static DHCP leases (half of them are usually off).
                  The only ones that don't have static IPs are devices that are connecting to the wireless access point, and I almost never have the WAP on.
                  And virtual machines on the main PC itself, which is a rare occurrence as well.

                  When this first started, I did try a packet capture on the LAN interface on pfSense before, while pinging from the PC.
                  It showed no traffic for the relevant address in the capture.
                  However, that has been a while ago, I will try that again next time.

                    More information:

                    This time I checked "disable all packet filtering" in "System: Advanced: Firewall and NAT" after being unable to connect.
                    It did not make a difference, I still couldn't connect.
                    FYI, the time the PC was powered off this time was 5 hours.

                    However, I re-ran packet captures (with "disable all packet filtering" back to unchecked I think), and I must have done it incorrectly last time, since it showed some traffic this time:

                    • On the LAN/BRIDGE0 bridge interface, it shows ARP broadcast requests from the main PC and ARP replies from pfSense LAN/BRIDGE0 to the main PC

                    • On the OPT2/em2 interface that the main PC is connected to, it only shows ARP broadcast requests from the main PC, but no replies.

                    So for some reason pfSense is able to direct the OPT2/em2 ARP broadcast to LAN/BRIDGE0, but it doesn't  forward the ARP reply from LAN/BRIDGE0 to OPT2/em2.

                    I did run a ping from another PC to pfSense to confirm that ARP replies do normally show up on the specific OPT/em interface, and it shows that normally they do.

                    FYI, in case it is relevant for this, in "System: Advanced: System Tunables", I have all the settings set at their defaults, except "net.link.bridge.pfil_member" is set to 0 and "net.link.bridge.pfil_bridge" is set to 1.

                      Hmm. If you run ifconfig at the console do the bridge member interfaces show as 'promiscuous mode'?

                      Why are arp replies from LAN not appearing on OPT2? Perhaps because the bridge device thinks it has a route the main PC via some other interface? Maybe try packet captures on other bridge members to see if replies are ending up on the wrong interface. Just speculation.  ;)

                        The first post shows output from ifconfig, it shows PROMISC in the interfaces flags of the bridge member interfaces.
                        I will re-run it next time to make sure.

                        I will run package captures on the other interfaces next time to see if the replies end up elsewhere.

                        Thanks for the suggestions.

                          Packet captures on other interfaces don't show the missing ARP replies.

                          I re-ran ifconfig, and it shows the same info as in the first post.

                          However, I had success coaxing the connection back to life without a reboot.

                          I ran "ifconfig em2 down" and "ifconfig em2 up" and I think that got it going again.
                          However, I am not 100% sure, since I also played around with "ifconfig em2 -promisc" and "ifconfig em2 promisc", but nothing seemed to happen when I ran those.

                          Edit:
                          Tried it on a different PC, and it's the "ifconfig em3 up" after the "ifconfig em3 down" that does it.

                          Here is the log, I ran the ifconfig commands at 07:22:09 and 07:22:13.
                          It came back to life shortly after 07:22:13.

                            Hmm, interesting. I wonder why the interface stops responding yet nothing in the logs.  :-
                            Can you bring the interface back by unplugging and re-plugging the cable?

                              When I tried it in the past, unplugging and re-plugging the cable didn't make a difference, neither did switching to a different port.
                              I will try that again though next time.

                              I am wondering if it's not some sort of sleep or power saving mode that is enabled in the 2.1.1 nic driver that isn't in 2.1.0 (if such a thing exists)?
                              I haven't narrowed down the exact time threshold, but it seems consistent somewhere between 4 and 5 hours, so maybe it's some sort of sleep time setting (although I would think that would be much shorter).

                                Good question. The em drivers were updated for 2.1.1 so that's a distinct possibility. What are the actual chips in the NICs you have? Anything relevant in hw.em? This looks a likely suspect:

                                [2.1.2-RELEASE][root@pfsense.fire.box]/root(3): sysctl hw.em.smart_pwr_down
                                hw.em.smart_pwr_down: 0
                                

                                Anything suspect in dev.em?

                                  I'm not sure what to watch for.
                                  FYI, this was not taken while the problem was occurring.

                                    Hmm, very common NIC so should be reported if it was a driver issue.
                                    You have a lot of CRC errors on em0. Which interface is giving trouble?
                                    Try to get a set of data when it's stopped responding.

                                      The nic may be common, but perhaps not a lot of people use pfsense the way I do?
                                      Meaning, directly connecting PCs to the pfSense box rather than having a switch in the middle, in combination with completely unplugging the PC rather than leaving it powered off, but not unplugged.

                                      My main PC is connected to em2, but I have reproduced the problem with it connected to other interfaces and with other PCs on other interfaces.

                                      My WAN interface is em0, which is connected using WiMAX, don't  know if that explains the number of CRC errors or not.

                                      I will try to get dev.em data the next time the problem happens.

                                      Edit:

                                      I tried unplugging and re-plugging the connection, that does not seem to solve the problem, but ifconfig em2 down followed by ifconfig em2 up does.

                                      Here is the dev.em data while the problem happens:

                                        I have a box that is quite similar in many ways, same NICs, and I often use it as you do, without a switch. I too have all six em NICs bridged together. However I haven't done so recently as I'm using as a test box with 2.2. Thinking back I'm not sure if I ever had that arrangement with 2.1.1/2.
                                        Interestingly I have experienced very similar behavior on that box but not on the em interfaces, on its one fxp NIC. That NIC will not negotiate a connection if it is powered up before the machine at the other end. In that case it was a harware (perhaps firmware) level issue where it would fail to negotiate a speed and duplex wiht the NIC at the other end resulting in no link. The link LED would flash intermittently as it tried and failed. It has no problem doing it it the other end is already powered up. I never found a good solution to it but you work around it by manually setting the link speed and duplex. Try that.

                                          I have played around with nic settings on the connecting PC before, and that didn't seem to make a difference, but I will try that again.

                                          I looked at some of the differences between the em drivers in 2.1.0 and 2.1.2.
                                          In 2.1.2 the version is 7.3.8, I think 2.1.0 might be 7.3.2.
                                          One thing I noticed is that the hw.em.eee_setting (Energy Efficient Ethernet) default might have changed.
                                          It now seems to default to 1 and I think it defaulted to 0 before.
                                          However I can't figure out by the somewhat cryptic code if that means it's now enabled or disabled.
                                          Anyway, I set hw.em.eee_setting=0 in /boot/loader.conf.local and rebooted, but that unfortunately didn't fix it.

                                            Damn that seems like a great suspect. The sysctl had changed after boot?

                                            In my case you could see the NIC wasn't making a connection as ifconfig showed 'no carrier' I don't belive you're seeing that though.
